To all whom t may concern,.-

Be it known that I, JosIAH E. NIGHTIN- GALE, a citizen of the United States, residing at Danvers, in the county of Essex and State of Massachusetts, have invented, new and useful Improvements in Machines for Meas-` lowing is a specification.

This invention relates to improvementsin uring the Areas of Surfacesyof which the folmachines for measuring the areas of surfacesof the kind shown and described in the United States Letters Patent granted to William A. Sawyer April 4, 1882, No. 256,058; January 2, 1883, No. 269,962; October 2, 1883, No.

November 3, 1885, No. 329,597; and it con,- sists in arrangements of the levers which con neet the indicating device with thesegments i for the purpose of simplifying the measuring device by using `a less number of parts in a given length to measure the given area; also,

in means `for longitudinally adjusting ,-the front cross-bar, to which the framesor yokes containing the ljournaled measuring-wheels are pivoted for the purpose of longitudinally adjusting the i pinions of the measuringwheels properly relative to the toothed segments; also, in` means for vertically adjusting the front cross-bar for the purpose of causing the pinions to be held disengaged fromI the segments at.- all times when no hide or skin passes between the feed-roll and measuring-wheels and to cause an engagement between such pinions and segments the moment a skin or hide is fed between said feedroll and measuring-wheels 5 also, in means for vertically adjusting the feed-roll relative to the measuring-wheels, so as to compensate for variations in Athe thickness of `the hides or skins, to allow all the ineasuring-wheels to` drop simultaneously in contact with the feedroll and to cause all the pinions tospread f open fromthe` segments when the skin,` Vor v hide is not fed between said feed-roll and measuring-wheels; also,A in means f orverti` cally adjusting the-back `bar `and its rod,`

i upon which the pawls are hung for the puri i pose of properlyadjusting the pawls for enf gagements with the segments; also, in a novel construction of the yokes or frames in which `"the measuring-wheelsand pinionsjare jour-` naled for the purpose ofsupporting the axle Eside `of the, pinion, for the purpose of `pre- 1 venting saidj arm or yoke from being twisted, and thus causing the Wheel to move in a true vertical plane and causing the pinion to proplerly engage with its segment where a hide or skin is passed 4between the feed-roll andthe fmeasuring-wheels, and also in a novel construction of the pawls which engagethe segments for the purpose of enabling said pawls `to be readily removed from the rod on which they are hung whenever it is desired to repair' .or sharpen said pawls without the removal iof any of the pins onthe rod which locate the lpawls in position relative to the segments.

In practice I prefer to make on each bracket L a lug or ear Z4, through which is screwed a` `while the hide is passing through, which would-cause an imperfect measurement thereof. According to myV invention, however, the pawls when strung upon the rod Z may be adjusted as may be necessary 'to or away from the toothed segments to the proper position in which they will engage the same accurately and with nicety. Furthermore, in the event, as will occur in constantuse of the machine, the noses of the pawls which engage the teeth lof the segments become worn it is not necessary to remove the pawls; but by properly adjusting the backbar L the worn pawls may be brought into the proper e engagement with theteeth of the segments.

I have shown in the drawings and described in this speciication certain mechanical means in machines of this kind for vertically adj usting the feed-roller, for' vertically and horizontally adjustingthe front` bar, and for ver?V tically adjusting the back bar,-andalthough such mechanism is preferable I desire to state that I do not wish to confine myself to such exact mechanism `for adjusting the said parts,

as other well-known devicesandmecnanism may be used for such purposes without der parting from the essence of `my invention.'

In machines of this kindthepawlshLthat.

engage the segments N, are pivotally arranged upon a rod Z andlocated at a proper distance apart by means of pins Z6, secured tosaid rod and projecting each into a slot m in the hub m of said pawl. It is often necessary to remove one or more of saidpawls from the supporting-rod for the purpose of `sharpening or repairing said pawls, and this could heretofore only be accomplished bythe removal of the guide-pins from the supportingrod,which is a very difficult operation. `'Ioavoid such objection and to enablethe pawls to be readily removed from the said roll and replaced thereon after being sharpened or repaired, `I construct the said pawls as follows: `I make on one side of the-hub m ofthe pawla cut-away ortion mf lar e enough to ermit the in Zl- P g s P D to pass through it when the pawl is being turned and moved longitudinally on the rod l.` Tov remove one or more of the pawls, it'is only necessary to remove one or more ofthe rod-bearings l, after which `the pawls are` turned on the rod l',.so that thecut-away` portion m on the pawl coincides or comes in alinement with the pins Z6, when the pawl or pawls may readily be withdrawn from the rod Z and as readily be replaced thereon after being repaired or sharpened. Each segment N has its spindle n journaled in the end of a leverO, which is hung at O and connected to the yoke or frame G for the measuringwheel F by means of a rod O", as is common in devices of this kind. l

P in Figs. 2 and 3 represents the hide or skin the area of which is to be measured while it is passed between the feed-roll and measuring-wheels.

Q is the graduated dial, secured in a suitable manner to the upper cross-beam B. q is the index, secured to the shaft of the pinion q', the teeth of which mesh in the teeth of the" segment q" on one end of the beam g3, which is pivoted at g4 and provided with a balanceweight g5, as is common in devices of this kind.

In connectionwith said indicating device I structed and carried out as follows: Q6 is a link connected in a suitable manner to the beam Q3 and pivotally connected in its lower end to the lever R, as is ycommon in measur-` ing-machines of this kind. The longer end of the lever .R is pivotally connected to a lever R'. The shorter end ofthe lever R is pivotally connected to a vlever R, and to the` shorter end ofthe latter is pivotally con-` nected a lever- R3, similar to the one marked R on thelonger end of the lever R. The ends of1 the levers R R3, as well as the longer -end of the lever R", are pivotally connected tolevers R4. The shorter ends of the levers j R4 are pivotally connectedto levers R5, from the j ends of which are suspended the pulleys fr r. Similar pulleys are also suspended from the longer ends of the levers R4, as shown in Figs. 1, 8, 9, and l0. Over each pulley r is carried a chain S, the lower ends of which are secured to the hubs 0f twoadjacent seg- IIC ments N in the series, as shown in Figs. l and 3.` By this arrangement of levers, as above stated, the system issimplitied, and I am thereby enabled to use a less number of parts in a givenlength for accurately measuring a given area.

Theoperation of the machine is similar to that shown and described in the aforesaid Sawyer patents.
